Just seeking some opinions here...

What phylogenetic position of the following basal tetanurans? Which of them can be classed as Torvosaurids? Spinosauroids? Carnosauria? Or just plain basal Tetanurae?

1) Cryolophosaurus
2) Monolophosaurus
3) Eustreptospondylus
4) Afrovenator
5) Piatnitzkysaurus
6) Sinraptor/ Yangchuanosaurus
7) Metriacanthosaurus
8) Valdoraptor

any information regarding their similarities/ differences to other much more well-known taxa (eg. Giganotosaurus, Allosaurus, Acrocanthosaurus) would be much appreciated.
